In this AIA Austin Homes Tour episode of TALKdesign, I sit down with architect Murray Legge, FAIA, to walk through his South 3rd Street project in Austin, Texas. We talk through how he quadrupled the living space of a compact 800-square-foot 1930s cottage on a tight 3,500-square-foot urban lot. Rather than building outward and losing the garden, Murray added three stories behind the original bungalow, wrapping the extension in natural cork insulation to create a quiet, healthy family home. Whether you are planning a renovation, looking at non-toxic building materials, or interested in small-footprint architecture, this episode covers practical ways to prioritize quality of space over total square meters. 💬 WHAT WE EXPLORE IN THIS EPISODE: • Adding three stories behind a vintage bungalow while navigating site limits, street character, and a 15-foot powerline setback. • Using natural cork cladding as a hydrophobic, fire-retardant insulator that off-gasses zero toxins and smells subtly of toasted wood when warmed by the sun. • Bringing rooflines down near ground level so the building envelope feels accessible at human scale. • Designing interior flow with sunken living areas, hidden bookcase doors, custom perforated steel stairs, and timber joinery. • Managing passive solar orientation: capturing morning east light, using soft north daylight, and blocking western heat—including how solar orientation flips between the Northern and Southern Hemispheres. • Improving indoor air quality by choosing blown wood-pulp insulation over synthetic spray foam. ⏯️ CHAPTERS / TIMESTAMPS: 01:10 Visiting architecture in person 05:00 South 3rd Street: Extending an 800 sq ft 1930s cottage 07:05 Why wrap a house in natural cork insulation? 09:15 Designing around strict powerline setbacks and urban site limits 13:30 Bringing rooflines down to human scale 15:40 Inside the flow: Sunken living rooms and hidden doors 22:15 Quality vs quantity: Rethinking square footage and budgets 25:20 The treehouse bathroom and natural light integration 28:00 Passive solar orientation: Northern vs. Southern Hemisphere light 32:20 Non-toxic building: Blown wood-pulp insulation and healthy air 35:40 The top-floor loft and framing views 38:25 Wrapping up About our guest: Murray Legge, FAIA Murray Legge graduated from the Cooper Union School of Architecture in New York City and is a Fellow of the American Institute of Architects.
